category: bugfix

CVE: NA

--------------------------------

commit e65af5403e462ccd7dff6a045a886c64da598c2e upstream.

usbnet provides some helper functions that are also used in
the context of reset() operations. During a reset the other
drivers on a device are unable to operate. As that can be block
drivers, a driver for another interface cannot use paging
in its memory allocations without risking a deadlock.
Use GFP_NOIO in the helpers.
